2 Claims. 1

My invention relates to improvements in screen equipment for windows,the primary object in view being to provide for the usual windowinexpensive and easily installed roll screen equipment adapted forunrolling of the screen by merely raising the lower sash and for rollinginto a hidden, safely stored, readily accessible position when not inuse, all to the end that inconvenient and frequently dangerous fittingof separate screens in windows may be dispensed with, also storing ofwindow screens in remote places. 7

Other and subordinate objects also comprehended by my invention,together with the precis nature of my improvements, and the manifoldadvantages thereof, will be readily understood when the succeedingdescription and claims are read with reference to the drawingsaccompanying and forming part of this specification.

In said drawings:

Figure 1 is a view in elevation, partly broken away, and shown insection, of a window equipped according to my invention in the preferredembodiment thereof,

Figure 2 is a view in vertical section taken on the line 2-2 of Figure 1and drawn to an enlarged scale,

Figure 3 is a fragmentary view in perspective of the lower sash and thescreen, together with the pintle rods,

Figure 4 is a view in horizontal section taken on the line 44 of Figure2, and

Figure 5 is a detail view in vertical section taken on the line 5-5 ofFigure 3.

Referring to the drawings by numerals, my invention has been showntherein as forming part of the equipment of the usual window, with upperand lower sashes 2 vertically slidable between a parting strip 3 andouter and inner stops 4, -5 in a frame 6 set into a wall I and includinga sill member 8.

According to my invention, a trough 9 of any suitable material, forinstance, sheet metal, or plastic, is fitted in the wall 1 immediatelybelow the sill member 8 to extend along said member with its top closedthereby. Preferably, the trough 9 is provided with a front, upper offsetportion Ill fitting in a slot II in the Wall 8. The usual lower,detachable, trim panel l2 covers the slot A moisture drain pipe l3extends laterally from the bottom of the trough 9 to the outside of thewall 1.

A spring wound roller M is suitably mounted at its ends in bearingblocks |'5 in the ends of the trough 9. The roller I4 is preferably ofthe type used for window shades, but is freely rotatable in oppositedirections, respectively, in the bearing blocks I5, and is provided withcircumferential end flanges l6 for a purpose presently seen.

A flexible screen, preferably of light, plastic, mesh material, issuitably connected at one edge thereof to the roller M to be wound upthereby. The opposite edge of the screen I! is detachably attached, aspresently described, to the bottom of the lower sash 2, A longitudinalslot |*8 in the sill member 8 permits the screen I! to be pulledupwardly off the roller l4 and out of the trough 9 through said member8.

The plastic mesh IQ of the screen I! is bounded by a flexibl steelbinder 20 suitably attached to said mesh as by crimping over the edgesof the same. As will be understood, the screen I1 is designed toslidably fit in the frame 6 between the parting strip 3 and the innerstop 5.

For detachably attaching the before mentioned edge of the screen [1 tothe sash 2, a pair of hinge barrels 2|, 22 are formed on the binder 20,forming said edge, and adjacent to opposite corners of said screen. Athin strip 23, preferably of metal, is secured in any suitable manner tothe bottom edge of the lower sash 2, as by imbedding therein, and hasformed thereon pairs of hinge barrels 24, 25 at opposite ends of saidstrip, spaced apart in each pair to accommodate the barrels 2|, 22therebetween. Suitable pintle rods 26, 2'! are extended slidably throughthe pairs of hinge barrels 24, 25 and the hinge barrels 2|, 22 forremoval by sliding toward the vertical center of the sash 2. A flexible,resilient fin 28 on the binder 20, between the hinge barrels 2| 22,bridges the space between the pairs of hinge barrels 24, 25, but may beflexed asid to permit the pintle rods 26, 21 to be removed.

A pair of guard strips 29, 30 of thin metal, preferably, are provided inthetop of the trough 9 to extend from end to end thereof upon oppositesides of the screen I! with edge rollers 3|, 32 suitably mounted thereonto bear against 0pposite sides of said screen. The strips 29, 30 may befixed in any desired manner to opposite sides of the trough 9, andtogether with the rollers 3|, 32 serve to prevent insects from fallinginto the trough 9.

The inner or front side 33 of the trough 9, throughout the portion I0,is designed to fit flush against the trim panel l2 and the rear, upperedge of the trough 9 to seat against the bottom of the sill member 8, asat 34, whereby. together with the fit of said portion in the slot II,the trough is securely held in proper position in the wall I.

As will now be seen, my invention provides a roll up screen arranged tobe unwound from below the sill of the window by merely raising of thelower sash and to screen the window below said sash. Obviously, thescreen may be wound up, when the sash is lowered, into housed, protectedand hidden position. The equipment involved is simple in construction,requires few parts, and may be installed permanently in any usual windowstructure at a comparatively low cost. By removing the pintle rods 26,21, the

screen I! may be dispensed with, when no screen is desired, and will bewound up until barrels 2|, 22 engage the rollers-3|,

on top thereof where the same may be grasped by a suitable implement sothat the screen may be pulled up out of the hinge T ,2 32 and lie a theslot II and again attached to the sash 2, when screening is desired forthe window. When the hinge barrels 2|, 22 engage-- the rollers 3|, 32,said rollers act as stops limiting winding up of the screen 11.Obviously, the described screen equipment may be duplicated at the topof the window in connection with the upper sash l. V The foregoing will,it is believed, sufllce' to impart a clear understanding of my inventionwithout further explanation.

Manifestly, the invention, as described, is susceptible of modificationwithout departing from the inventive concept, and right is hereinreserved to such modifications as fall within the scope of the appendedclaims;

What I claim is: j

1. A roller screen for a window connectable to a sliding sash of saidwindow and adapted to be unrolled by upward sliding of said sashcomprising a strip of flexible screening, a pair of hinges on one end ofsaid strip spaced apart along said end with aligned hinge pintlestherein removable by sliding toward each other, said hinges beingattachable to said sash, and a member on said end of the stripinterposed between said hinges to prevent removal of said pintles, andbendable out of interposed position to permit said pintles to be removedfor detaching said end of said strip from said sash.

2. A roller screen for a window connectable to a sliding sash of thewindow and adapted to be unrolled byupward sliding of said sashcomprising" a strip of flexible screening, devices at one end of saidstrip attaching the same to said sash and detachable from said sash tofree said strip from the sash, means for rolling up said strip underspring tension when freed, and means to limit "such rolling up of saidstrip comprising a pair of fixed platesbelow said sash spaced apart withconfronting'edg'es and a pair of guide rollers rotatably mounted on saidedges and frictionally engaging opposite sides of said strip, saidrollers engaging said devices when detached to stop rollingup of thestrip.
